摘要
使用１ｉｎ光学格式的ＣＣＤ成像系统比较容易获得高分辨率图像，而２／３ｉｎＣＣＤ成像难以达到高分辨率，它的体积和功耗却小得多。因此，研究小型ＣＣＤ的高分辨率成像技术一直是十分关注的问题。分析了在欠抽样的情况下，既提高分辨率又抑制混迭失真的空间偏置成像的原理、方法。介绍两种成像系统：ＲＧＢ高分辨率成像和ＤＧ高分辨率成像。使用２／３ｉｎ１３０万像素的ＣＣＤ，可获得１０００ＴＶ线的高分辨率图像，文中还比较了两种成像系统的性能。
Using a 1-inch CCD imaging system make it easy to obtain a ligh resolution , mage , but 2/3- high CCD camera which is compact and low con- sumption has not a high resolation. Therefore , The method of improving the resolution of compact CCD has been ottentioneel. The method and prinde of im- proving the resolution , meanwhile suppressing alias signals under the condition of the undersampling is analised in the paper , The RGB high resolution sys- tem and DG high resolution system is introduced. Using 2/3-inch. 1 30 million pixels CCD sensor make it easy to obtain a high resolation image. The prop- erty of the two system is compared in the paper.
